Phenomena in the froth phase of flotation — A review
Abstract. The froth phase is one of the main components of froth flotation as it defines both the quality of the end product and overall efficiency. The performance of the froth depends on a number of sub-processes that interact in very complex ways, and it is a great research challenge to explicitly name the role of each of these sub-processes.

Froth flotation is a complicated process which is difficult to establish its first-principle model. Due to the fluctuations in the grade of raw ore, adaptively adjusting the set-points is extremely important in the flotation process. The inappropriate set-points easily lead to the instability of the process. This paper presents a fuzzy association rule-based …
